oxygenation

  1. ventillation
    airways are open and able to transport air to and from the lungs
  2. gas exchange
    o2 and co2 are exchanged at the alveolar/cap membrane in the lungs
  3. atelectasis
    collapse of alveolia, prevents normal gas exchange
  4. perfusion
    CV system pumps oxygenated blood to the tissue and returns deoxygenated blood to the lungs
  5. what transports o2 and co2
    hemoglobin
  6. what are early S/S of hypoxia
    vital signs are elevated at first
  7. what is the % of o2 in room air
    21
  8. FiO2
    fraction of inspired air
  9. SpO2
    o2 sat of arterial blood
  10. PaO2
    partial pressure of alveolar o2 

    -measured with ABG
  11. green

    • up to .50
  16. partial rebreather

    FiO2
    • resivoir bag must be inflated with O2
    • .60-.90 depending on how many valves are open
